title: Exoantigen test for identification of Petriellidium boydii cultures.
abstract: Cultures of Petriellidium boydii were serologically identified by detection of their exoantigens with an immunodiffusion procedure. The technique, which is specific and sensitive, allowed the rapid identification and differentiation of 12 isolates of P. boydii from numerous other morphologically similar Hyphomycetes. The antigen-antiserum reference system and the production, by two different techniques, of exoantigens used in the identification of P. boydii are described.
